Ith'amar (Heb. Ithamar', אַיתָמָר, palm-isle; but according to Furst, not high, i.e. little; Sept. Ι᾿θάμαρ; Josephus Ι᾿θάμαρος, Ant. 8, 1, 3), the fourth and youngest son of Aaron (1Ch 6:3). B.C. 1658. He was consecrated to the priesthood along with his brothers (Ex 6:23; Nu 3:2-3); and after the death of Nadab and Abihu (Le 10:1 sq.), as they left no children, he and Eleazar alone remained to discharge the priestly functions (Le 10:6,12; Nu 3:4; Nu 26:60 sq.; 1Ch 24:2). Nothing is individually recorded of him, except that the property of the tabernacle was placed under his charge (Ex 38:21), and that he superintended all matters connected with its removal by the Levitical sections of Gershon and Merari (Nu 4:28). The sacred utensils and their removal were entrusted to his elder brother Eleazar, whose family was larger than that of Ithamar (1Ch 24:4). Ithamar, with his descendants, occupied the position of common priests till the high-priesthood passed into his family in the person of Eli, under circumstances of which we are ignorant. SEE ELI. Abiathar, whom Solomon deposed, was the last high-priest of that line, and the pontificate then reverted to the elder line of Eleazar in the person of Zadok (1Ki 2:27). SEE HIGH-PRIEST. The traditionary tomb of Ithamar is still shown near that of his brother Eleazar in the hill of Phinehas (Schwarz, Palest. p. 151). A priest by the name of Daniel, of his posterity, returned from Babylon. (Ezr 8:2; Ezr 1 Esdr. 8:29).
